On the evaluation of illumination compensation algorithms
Multimedia Tools and Applications, 2017This paper presents a comparison framework for algorithms that can diminish the effects of illumination in images. Its main objective is to reveal the positive and negative characteristics of such algorithms, allowing researchers to select the most appropriate one for their target application.

Evaluation of a hearing compensation algorithm
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002A new hearing compensation algorithm based on a homomorphic multiplicative AGC (automatic gain control) is evaluated and compared against commercially available digitally programmable analog hearing aids. Both quantitative (speech recognition threshold and speech discrimination) and qualitative tests (estimation of perceived quality) were used in the ...

An algorithm for design of beam compensators
International Journal of Radiation Oncology*Biology*Physics, 1989Beam compensators are optimally designed to give a uniform dose to any plane or midsurface that intersects a single beam, or to give a uniform dose to the volume defined by the intersection of two or more beams. The primary and scatter components are taken into account separately, as well as the patient's shape and internal heterogeneities.

A Variational Algorithm For Motion Compensated Inpainting
Procedings of the British Machine Vision Conference 2004, 2004A novel variational algorithm is developed for video inpainting. Within a Bayesian framework, using standard maximum a posteriori to variational formulation rationale, we derive a minimum energy formulation for the estimation of a reconstructed sequence as well as motion recovery.

A Dispersion-Compensated Algorithm for the Analysis of Electromagnetic Waveguides
IEEE Signal Processing Letters, 2021Electromagnetic waveguides have dispersive properties, meaning the phase and group velocities change with frequency. This dispersion leads to broadening in the time-domain impulse response, which can make it difficult to separate adjacent signals if they overlap. To help address this issue, we present a dispersion-compensated algorithm for the analysis

Generic algorithms for motion compensation and transformation
SPIE Proceedings, 2008In this paper, we propose algorithms that map the low-level motion compensation and transformation functions of MPEG-1/2, H.263/MPEG-4 ASP and H.264/MPEG-4 AVC video codecs onto common workflows. This way, a single discrete implementation of luma prediction, chroma prediction and residual transform stages is sufficient for all covered video coding ...

Compensation of the RLS algorithm for output nonlinearities
IEEE Transactions on Automatic Control, 1999Summary: It is shown how the recursive least squares (RLS) algorithm can be modified to compensate for a priori known errors of linearity in the output measurement. A novel signal model is used for this purpose. Only the nonlinear effects are modeled by an output error model, and much of the output measurements are used directly in the regression ...
